Experts at SophosLabs™, Sophos's global network of virus, spyware and spam analysis centers, have warned users to be wary of unsolicited emails claiming to contain obscene pictures and sex movies.

The W32/Nyxem-D worm (also known as Email-Worm.Win32.VB.bi or W32.Blackmal.E@mm) can spread via email using a variety of pornographic disguises, in an attempt to disable security software. If launched it tries to disable a number of anti-virus and firewall products, and attempts to harvest other email addresses from the infected computer, in an effort to spread itself further.

Subject lines used in the malicious emails include the following:

*Hot Movie*

Fuckin Kama Sutra pics
Fw: SeX.mpg
Fwd: Crazy illegal Sex!

Miss Lebanon 2006

"Companies should educate their users to practise safe computing - that includes never opening unsolicited email attachments and discouraging the sending and receiving of joke files, pornography and funny photographs and screensavers," said Graham Cluley, senior technology consultant for Sophos
